cQnce
cQnce (pronounced /ˈsiːkwəns/) is human authorization infrastructure for high-risk automated actions. Applications, automations and AI agents call its API (e.g. POST /v1/requests) to pause a sensitive operation such as a payment, refund or production-access change, route a pre-action approval request to verified human approvers on mobile using parallel, serial, majority or chain routing rules, and resume securely through ECDSA P-256 signed decisions and HMAC-SHA256 signed webhooks. It offers six SDKs plus an MCP server for AI-agent tool approval and a free developer plan. cQnce is operated by TECH S.r.l. (VAT IT03532980103), Genova, Italy.
cQnce publishes 15 API contracts indexed on the APIs.io network, including Agents – Admin API, Agents – Self API, Alarms API, and 12 more. Tagged areas include Company, Human-in-the-Loop, Approvals, Authorization, and AI Agents.
The cQnce catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
cQnce’s developer surface includes changelog, sandbox, authentication, getting-started guide, API reference, engineering blog, pricing, and 36 more developer resources.
